Politico’s Tim Alberta and Rachael Bade drop a blockbuster: “Despite several landmark legislative wins this year, and a better-than-expected relationship with President Donald Trump, Ryan has made it known to some of his closest confidants that this will be his final term as speaker. … He would like to serve through Election Day 2018 and retire ahead of the next Congress. This would give Ryan a final legislative year to chase his second white whale, entitlement reform, while using his unrivaled fundraising prowess to help protect the House majority—all with the benefit of averting an ugly internecine power struggle during election season.”

Speculation has been swirling that Ryan could step down once “he’s harpooned his personal white whale of tax reform,” as HuffPost put it.

The Wall Street Journal reports that the tax cuts and economic environment are prompting U.S. companies to go on a buying binge: “Mergers and acquisitions announced by U.S. acquirers so far in 2018 are running at the highest dollar volume since the first two months of 2000, according to Dealogic. Thomson Reuters, which publishes slightly different numbers, puts it at the highest since the start of 2007.”

Health care spending in the U.S. will grow at an average annual rate of 5.5 percent from 2017 through 2026, according to new estimates published in Health Affairs by the Office of the Actuary at the Centers for Medicare and Medicaid Services (CMS).

The projections mean that health care spending would rise as a share of the economy from 17.9 percent in 2016 to 19.7 percent in 2026.

Margot Sanger-Katz and Jim Tankersley in The New York Times: “The deal struck by Democrats and Republicans on Monday to end a brief government shutdown contains $31 billion in tax cuts, including a temporary delay in implementing three health care-related taxes.”

“Those delays, which enjoy varying degrees of bipartisan support, are not offset by any spending cuts or tax increases, and thus will add to a federal budget deficit that is already projected to increase rapidly as last year’s mammoth new tax law takes effect.”

Congress passed a law in 2015 requiring the IRS to use private debt collection agencies to pursue “inactive tax receivables,” but the financial results are not encouraging so far, according to a new taxpayer advocate report out Wednesday.

In fiscal year 2017, the IRS received $6.7 million from taxpayers whose debts were assigned to private collection agencies, but the agencies were paid $20 million – “three times the amount collected,” the report helpfully points out.
